i know it sucks. it's only my 3rd/4th?! attempt at a vexel/vector...but you need crappy ones like these so the awesome real vectors can look more amazing (: it's kate bosworth but it doesn't really look like her. uh, yeah. try not to diss too much :$
This is a very good vexel!! The only thing I'd consider if you were making blonde hair is to not do as much "yellow" but lighter shades of brown? I found it helps me, but i dunno. I really love the skin shading, and the lips and eyes are fantastic! :)
